Abstract
The use of a specific molybdenum-silicon-boron alloy and a particular production process in which powder is used makes it possible to achieve components which have a particular fiber-matrix structure and can be used for high-temperature applications and can also be produced inexpensively.
Description
- This application is the US National Stage of International Application No. PCT/EP2016/059342 filed Apr. 27, 2016, and claims the benefit thereof. The International Application claims the benefit of German Application No. DE 102015209583.5 filed May 26, 2015. All of the applications are incorporated by reference herein in their entirety.
- The invention relates to a specific molybdenum-silicon-boron alloy, a production process and a component.
- Mo-(x)Si-(y)B alloys represent a potential opportunity for making hot gas components for a gas turbine which go beyond the use window of classical nickel-based superalloys. These alloys offer a use window up to a hot gas temperature of 1973K, with a coating up to 2073K. Widening of the use range by up to 300K, associated with a corresponding increase in the efficiency, compared to alloys used hitherto is thus possible.
- The processing of these alloys can be carried out by a powder-metallurgical route, or else by means of zone melting. Zone melting leads, because of the temperature gradient which arises, to formation of a fiber-matrix structure which is impressive due to its excellent creep properties at temperatures above 1273K.
- However, both processes allow only formation of simple test specimens, so that the potential of these alloys cannot be exploited at present.
- It is therefore an object of the invention to solve the abovementioned problem.
- The object is achieved by an alloy, a process and a component as claimed.
- It is proposed that a novel Mo—Si—B alloy be processed by means of an additive manufacturing (AM) process such as Selective Laser Melting (SLM). Furthermore, the processing by means of an energy beam, for example a laser beam, in conjunction with the outward heat conduction conditions in the powder bed allows the formation of a temperature conduction gradient which in turn is advantageous for the optionally desired formation of a fiber-matrix structure in which the individual phases are present as Moss/Mo5SiB2/Mo3Si structure.
- An optional alloying-in of zirconium (Zr) (0.5 at %-2 at %) leads to an advantageous increase in the fracture toughness of the alloy or of the component.
- Furthermore, the AM process offers, compared to the powder-metallurgical process, the advantage that oxygen is very largely kept away from the workpiece. This has a positive effect on the materials properties.
- The process data for production by means of the AM process are advantageously:
-
- Alloy: Mo-(x)Si-(y)B,
- where x=3-19 at % and y=1-13 at %,
- preferably x=13-18 at % and y=8-12 at %,
- optional addition of zirconium (Zr) z=0.5 at %-2 at %,
- preferably z=1 at %,
- Particle size: 10-60 μm, either gas-atomized or milled,
- as possible processing window:
- Scanning speed: 400 mm/s-2000 mm/s,
- preferably 1000 mm/s-1500 mm/s,
- Laser power: 80 W-250 W,
- preferably 100-170 W.
